Combined spliced door frame

Abstract

The invention provides a combined spliced door frame. A vertical pillar and a beam of the combined spliced door frame are each provided with steps corresponding to a door. The vertical pillar and the beam are each integrally formed through medal plates. The vertical pillar end of the vertical pillar and the beam end of the beam are spliced and combined, an inserting groove is formed in the low step of the vertical pillar end, and the high step of the vertical pillar end inwards retracts to form a first platform. A first inserting plate is arranged on the first platform in an extending mode, an inserting hole is formed in the high step of the beam end and matched with the first inserting plate in a corresponding mode, and the inserting hole is provided with an axial hole width for movement of the first inserting plate. The high step of the beam end is matched with the first platform in a corresponding mode, the low step of the beam end inwards retracts to form a second platform, and a second inserting plate is arranged on the second platform in an extending mode and matched with an inserting groove in a corresponding mode, and the second platform is matched with the low step of the vertical pillar end in a corresponding mode. Under the uncombined state, the vertical pillar and the beam are separated, conveying and moving are convenient, the more door frames are contained in the same space, the space is effectively utilized, and cost for conveying, storing and the like is reduced; and during crossed assembly combination, assembly is convenient, the structure is stable, and extra connecting pieces are not needed.

Description

technical field [0001] The invention relates to a door frame, in particular to a combined and spliced ​​door frame. Background technique [0002] The door frame has a border (that is, a column) and an upper sill (that is, a beam) that surrounds the sides and top of the doorway, and is embedded in the wall to support the door leaf. Door frames are generally made of wood or metal materials. For door frames made of metal materials (such as for anti-theft doors, etc.), the door frame is welded to form an integral door frame, which is troublesome in the transportation and handling process and takes up a lot of space. The number of integral door frames in the space is small. If a separate frame and upper sill are used for transportation, it will be troublesome to weld during installation. SUMMARY OF THE INVENTION [0003] In view of the technical problems in the background technology, the technical problem solved by the present invention is to provide a combined splicing door f...
